Exemption 12555

Navigation Accuracy Category for position and Navigation Integrity Category Exemption (12555)

The FAA has granted Exemption 12555 with a strict, limited timeframe in which operators must equip with new navigation receivers. Exemption 12555:

  • does not exempt the requirement for ADS-B Out equipment to be installed and operational on aircraft flying in ADS-B rule airspace starting January 1, 2020.
  • does allow for the extended use of an older type of GPS navigation receiver already installed in some aircraft. All other ADS-B Out equipment requirements must still be met and operational by January 1, 2020.
  • was granted because the kind of GPS navigation receivers suitable for transport category aircraft that meet the ADS-B Out Rule requirements will not be available for purchase or installation in sufficient quantities until closer to 2020.
  • imposes certain conditions, limitations and additional pre-flight responsibilities on the operators.
